1/Insecticidal soap : a universal pest solution

A popular homemade insecticide, insecticidal soap consists of soap oil and water. Ideal for treating a wide range of pests, this quick and easy solution can be made by mixing 1 teaspoon of soap oil with two cups of warm water in a spray bottle.

Avoid using dishwashing soap containing degreasers or bleach as they may harm your plants. Use the mixed solution within a day for maximum efficacy. This environmentally friendly spray works exceptionally well against aphids, lacebugs, leafhoppers, mealybugs, and thrips.

2/Neem oil bug spray : the organic choice for various pests

Neem oil is a trusted organic insecticide used for thousands of years to tackle everything from insects to fungi. Its popularity has soared as a natural solution, especially in India. To create a homemade neem oil bug spray, mix one to two tablespoons of pure, cold-pressed neem oil with a gallon of water.

You can also add one to two teaspoons of dish soap to help the solution adhere better to your plants. Neem oil not only removes pests such as mites, whiteflies, aphids, thrips, and mealybugs, but it also helps treat root rot when used as a soak. This terrific feature sets it apart from other commercial pesticides, which often harm birds, pets, and beneficial insects.

3/Vinegar spray : a simple yet effective solution

One of the simplest homemade bug sprays involves mixing one cup of vinegar with three cups of water. The strong odor emitted by this mixture reportedly repels ants and other scent-driven pests. For use on indoor plants, add a few drops of essential oil or infuse with lemon peel or rosemary sprigs to temper the vinegar smell.

4/Garlic spray: the pungent pest repellent

The scent of garlic and onions is known to keep aphids, slugs, and carrot flies away, making them excellent companion plants. You can easily make garlic spray by puréeing two garlic bulbs with one tablespoon of vegetable oil, straining the mixture, and adding one teaspoon of mild liquid soap with four cups of water. Evenly spray both sides of plant leaves with the garlic mixture and reapply every few days during infestations or use it as a deterrent every one to two weeks.

5/Tomato leaf spray : unleashing the power of alkaloids

Did you know tomato leaves contain an alkaloid compound that can be used to create a potent insecticide? Boil about one cup of chopped tomato leaves in two cups of water for around 20 minutes. Strain the liquid and dilute it with an equal amount of water before spraying it on your plants’ foliage. This mixture works wonders in repelling pests like aphids, mites, and whiteflies.
